JAMES E. EMERSON, OF TRENTON, NEW JERSEY.

Letters Patent No. 96,211, dated October 26, 1869.

IMPROVE-D BOOKING-CHAIR.

The Schedule referred to in these Letters Patent and making part of thesame To'all whom it may concern:

Be it known that I, J AMES E. EMERSON, of rirentou, in the county ofMercer, and 'State of New Jersey, have invented certain new and usefulImprovemonts in Rocking-Chairs; and I do hereby declare the following tobe afnll, lear, and exact description of the same, reference being hadto the accompanying drawings, making a part ot' this specilication, inwhich- Figure l represents a perspective view of the rocking-chairs' fFigure 2 represents a Vertical section through the same.

Similar letters of reference, where they occur in the separate figures,denote likeparts of the chair in both of=the drawings.

lily invention relates `to that kind of rocking-chair in which thc upperor seat-portion rocks upon the stationary under or supporting-portion,and 'of which there are many forms; and

M y invention consists in the' devices by which the seat and basefareunited, and on which the seat-portion rocks.-

And it .further consists in the use of pivot-points @and steps, for theseat to rock 1upon, which steps may also serve for oil-boxes, if oilingshould be found necessary. i

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawings.

A represents the stationary under portion of the chair, which Vmay beconstructed in any of the usual well-known and substantial ways, andwhich I prefer to make rounded or circling on top, so that a circularconcave seat will tit and move over it, the joint hetween the two heiligcovered by a moulding, a, which prevents theclothes of the user frombeing` caught therein, or trom pinching the iingers.

The uppe` portion B of the chair, which consists of the seat b,arm-supports c c, and back d, may be made, and upholstered, if sodesired, in any of the usual well-known ways, the side-pieces being,howere curved out, so as to snugly tit over the rounded part of thestand or stationary under portion.

On the rail or rung-pieces of the under stationary portion A, there`are' arranged steps, e e, which are cast with depressions or recessesin them, as shown by the dotted lines thereon, which form boxes, and inwhich the projecting points on the ends of the V or U-shaped supports GC, that are fastened to the upper or seat-portion B of the chair, enterand are supported, and upon which points, like the knife-edge ofascale-beam, the seat-portion rocks.

In the supports or braces C are made circular slots, ff, through which ascrew, stud, or pin, c', is passed into the plate that margins thesteps, which connection admits of therocking of the seat-portion uponthe points in the steps, and without a pivot-pin to work on, and stillimite the upper and under portions, so that the chair may be moved aboutwithout the two parts separatino'.

Should it become necessary at any time to oil the hearing-points ouwhich theJ seat rocks, it may be done without liability of oiling`or'soiling the carpet or door, jas the steps are boxes capable ot' holdinga. drop or more of oil withoutl allowing it to escape.

From the upper cross-piece I) of the stationary portion A, a coiledspring, E, extends to and bearsagainst the front piece Foi' theseat-portion, the reaction of which spring moves or helps to move theupper portion in one direction, whilst its compression prevents the seatfrom going too far, or with a jar, in the other direction. i

rDhis spring may extend from Dto the rear piece G, and serve the samepurpose, or there may be two springs. one front and the other back, butone will be found to he enough.

lf the chair is required for a'stationary or a reclining-chair, it maybe'made either by means of a springholt, an., with a thumb-nut head, n,which will take into any one of a series of holes,o o o, in theseatportion, and there hold it firmly to the stationary under portion.

The bolt passes through a catch-piece, r, that has recesses or notches sin it, so that the bolt in being turned will draw out and be caught andheld out, when used as a rocking-chair, and can be turned further, whenit will shoot into one of the holes o, and then hold it rigid and in aninclined position, when so desired.

Having thus fully described my invention,

\Vhat I claim therein asinew, and desire to secure by Letters Patent, isv s The combination ot' the pivot-pieces -or supports C with the stepsc, for forming a rocking connection between the upper and under portionsof the chair, as described and represented.

Also, the combination of the pivot-pieces, steps, and spring, with theoscillating seat and stationary under portion, as and for the purposeherein described and represented.

Also, in combination with the pivot-pieces and steps, the concentricslot and set-screw, for admit-ting ofthe rocking mot-ion of the upperupon the under portion, without allowing them to separate` when beinglifted or carried, as set forth.
